1. CA Title 24 Building Code
IMPACTS ON LIGHTING AND LIGHTING CONTROLS TO GO INTO EFFECT
ON JULY 1ST, 2014

2. Summary of Significant Changes to
Nonresidential Indoor Lighting
 Increased number of steps for mandatory multi-level lighting controls
 New requirements for bi-level occupancy controls in some spaces
 In all buildings except offices, lighting must be shut off completely
during unoccupied times
 Automatic daylighting controls are mandatory in all primary daylit zones
with at least 120W of installed load, with fewer exceptions
 The threshold for when alterations must comply with the Standards has
been reduced from when 50% of the luminaires in a room are altered,
to when 10% of the luminaires in a room are altered
 A new category of alteration called “luminaire modifications in place”
has been added
 Demand responsive control systems are required in all buildings 10,000
square feet or larger

3. Mandatory Lighting Controls
 Mandatory nonresidential indoor lighting controls include the
following:
 Area controls: manual controls separately controlling lighting in each
area
 Multi-level controls: providing occupants with the ability to use all of the
light, some of the light or none of the light in the area
 Shutoff controls: automatically shutting off or reducing light output of
lighting when it is not needed
 Automatic daylighting controls: separately controlling some or all of the
lights in the daylight area from the lights that are not in the daylight area
 Demand Responsive Lighting Controls: installing controls that are
capable of receiving and automatically responding to a demand
response signal

4. Area Lighting Controls
 A manual override control for the occupants is required
 Each area enclosed by ceiling-height partitions requires a manual
switch or dimmer switch (if controlling dimmable luminaires) for ON and
OFF lighting controls
 Must be readily accessible to occupants and control functionality
cannot be overridden by other lighting controls
 Manual switch must be located in the same room or area with the
lighting that is being controlled by that lighting control
 If controlling dimmable luminaires, be a dimmer switch that allows
manual ON and OFF functionality, and is capable of manually
controlling lighting through all multi-level lighting control steps

5. Multi-level Controls
 Requirement applies to enclosed spaces larger than 100 sq. ft. and with
a connected general lighting load greater than 0.5W/ square foot
 Requires either continuous dimming or three intermediate levels
between on and off settings – change from one intermediate level
 Luminaires mounted at less than 24 feet over most hardscape areas will
have to include bi-level control and dim when no one is present
 LED luminaires and LED source systems requires continuous dimming 10-100%
 In addition to the multi-level controls, each luminaire in the space must
be controlled by at least one of 5 methods:
1. Manual dimming
2. Lumen maintenance – a strategy used to provide a precise, constant level of
lighting from a lighting system regardless of the age of the lamps or the
maintenance of the luminaires
3. Tuning – the ability to set maximum light levels at a lower level than full lighting
power
4. Automatic daylight control
5. Demand responsive lighting control

6. Automatic Shut-Off Controls
 Shall be controlled with one or more of the following automatic
shut-OFF controls when the space is typically unoccupied:
 Occupant sensing control
 Automatic time-switch control
 Signal from another building system
 Other control capable of automatically shutting OFF all the lights
 Separately controls the lighting for each floor
 Separately controls the lighting in each room (enclosed space) and
a control can control up to 5,000 sq. ft.
 Larger spaces will have more than one separately controlled zone
where each zone does not exceed 5,000 sq. ft.
 Exception: may not exceed 20,000 sq. ft. in following areas:
 Mall, auditorium, single tenant retail, industrial, convention center, arena

7. Occupancy Sensor Controls
 Required to shut OFF all lighting:
 Offices 250 sq. ft. or smaller
 Multipurpose rooms of less than 1,000 sq. ft.
 Classrooms of any size
 Conference rooms of any size

8. Occupancy Sensor Controls (cont.)
 Parking garages will have to incorporate occupancy sensors that
allow lighting on less frequently used levels to be switched off or
turned to a low level when no one is present
 Warehouses, library stacks and all corridors and stairwells must
incorporate “partial off” control that partially dims the lights when
space is unoccupied
 Controls will have to reduce lighting power in these spaces by at least
50% during unoccupied times

9. Daylighting – General Terms
 General Lighting
 Electric lighting that provides a uniform level of illumination throughout
an area, exclusive of any provision for special visual tasks or decorative
effect, exclusive of daylighting, and also known as ambient light.
 Window Head Height
 The vertical distance from the finished floor level to the top of a window
 Daylit Zone
 A region of space considered to be close enough to a source of
daylight such as a window, clerestory, roof monitor or skylight, where
luminaires can be dimmed or switched in response to available daylight

10. Definitions of Daylit Zones
 Three different types of daylit zones:
1. Skylit Daylit Zone
1. Rough area in building plan view under each skylight, plus 0.7 times the average
ceiling height in each direction from the edge of the rough opening of the skylight,
minus any area on a plan beyond a permanent obstruction that is taller than the
following:
1. A permanent obstruction that is taller than one-half the distance from the floor to the
bottom of the skylight
2. The bottom of the skylight is measured from the bottom of the skylight well for skylights
having wells, or the bottom of the skylight if no skylight well exists
2. Primary Sidelit Daylit Zone
1. The area on the building plan directly adjacent to each vertical glazing, one window
head height deep into the area, and window width plus 0.5 times window head
height wide on each side of the rough opening of the window, minus any area on a
plan beyond a permanent obstruction that is 6 feet or taller as measured from the
floor
3. Secondary Sidelit Daylit Zone
1. The area on a plan directly adjacent to each vertical glazing, two window head
heights deep into the area, and window width plus 0.5 times window head height
wide on each side of the rough opening of the window, minus any area on a plan
beyond a permanent obstruction that is 6 feet or taller as measured from the floor

11. Daylighting
 Luminaires providing general lighting in skylit zones and primary
daylit zones must be controlled independently to automatically
adjust lighting levels (using photosensors) through multi-level or
dimming control
 Photosensor controls through multi-level or dimming required in
secondary daylit zones
 Primary zone – starts at window pane and extends one window head
height back into the space
 Secondary zone – starts at the back edge of the primary zone and
extends a further two window head height types
 Primary and secondary zones must be controlled separately

12. Daylighting (cont.)
 Automatic Daylighting control and installation
 For each space the combined illuminance from the controlled lighting
and daylight shall not be less than the illuminance from controlled
lighting when no daylight is available
 In areas served by lighting that is daylight controlled, when the
illuminance received from the daylight is greater than 150 percent of
the design illuminance received from the general lighting system at full
power, the general lighting power in that daylight zone shall be
reduced by a minimum of 65 percent

13. Daylighting (cont.)
 Spaces requiring minimum daylighting (daylighting required) – must
meet all requirements:
 Space is directly under a roof
 Located in climate zones 2 through 15
 Has a floor area greater than 5,000 square feet
 Has a ceiling height greater than 15 feet
 Exemptions: spaces that have a general lighting system with a power density
less than 0.5W per square foot or is a function area that includes: auditoriums,
churches, movie theatres, museums or refrigerated warehouses
 Buildings with unfinished interiors – future enclosed spaces are exempt which
are planned to have a floor area less than 5,000 square feet and a ceiling
height less 15 feet

14. Daylighting (cont.)
 Prescriptive daylighting requirements
 At least 75% of the total space floor area shall be under Skylit Daylit Zone
or Primary Sidelit Daylit Zone
 The calculation of daylit zone area to show compliance with this minimum
daylighting requirement does not need to account for the presence of
partitions, stacks or racks other than those that are ceiling high partitions

15. Demand Response
 Automatic demand response capability for lighting systems in all
commercial buildings larger than 10,000 square feet, regardless of
space type – change from 50,000 square feet
 Lighting system must be capable of receiving and automatically
responding to standards-based message, such as OpenADR, to
reduce lighting power by at least 15% below the building’s
maximum lighting power during peek and demand times

Power Allotments
 Complete Building Method
 Area Category Method
 Most common
 Tailored Method
 Most commonly used for retail lighting
 Performance Method
 Allows trade-offs between building envelope or mechanical systems
that can let the allowed lighting power go higher than any other
method

20. Complete Building Method
 Only applied when all areas in the entire building are complete
 Building must consist of one type of use for a minimum of 90 percent of
the floor area of the entire building
 Allowed Indoor Lighting Power allotment for general lighting:
 Conditioned building: multiply sq. ft. of conditioned space of the building X
the applicable allotment of watts per square foot
 Unconditioned building: multiply sq. ft. of unconditioned space X applicable
allotment of watts per square foot
 Used only on projects involving:
 Entire buildings with one type of use or occupancy
 Mixed occupancy where one type of use makes up at least 90 percent of
the entire building (shall be assumed that primary use is 100 percent for
calculations)
 A tenant or space where one type of use makes up at least 90 percent of
the entire tenant space (shall be assumed primary use is 100 percent of
tenant space for calculations)

22. Area Category Method
 Can be used for multiple tenants or partially completed buildings
 “Area” defined as all contiguous spaces that accommodate or are
associated with a single primary function
 Area not covered by current permit is ignored
 Divides building into primary function areas
 Lighting Power Allotment determined by multiplying the area of each
function X the lighting power density for that function
 When areas are bounded or separated by interior partitions, the floor space
occupied by those interior partitions shall be included in any area
 The total allowed watts is the summation of the Lighting Power Allotment for
each area covered by the permit application
 Each function area in the building must be included as a separate area
 Boundaries between primary function areas may or may not consist of walls
or partitions
 It is not necessary to separate aisles or entries within function areas
 When used to calculate for an entire building – main entry lobbies, corridors,
restrooms, and support functions treated as separate function areas

23. Area Category Method (cont.)
 Additional Requirements
 If at the time of permitting for a newly constructed building, a tenant is
not identified for a multi-tenant area, a maximum of 0.6 watts per
square foot shall be allowed for the lighting in each area in which a
tenant has not been identified
 Classified as Unleased Tenant Area
 The allowed Indoor Lighting Power Density for each primary area is the
Lighting Power Density Value X the square feet of the primary function
 The total allowed indoor Lighting Power Density for the building is the sum of
the allowed indoor Lighting Power Densities for all areas in the building

24. Additional Lighting Power – Area
Category Method
 In addition to the allowed indoor Lighting Power calculated, the
building may add additional lighting power allowances for
specialized task work, ornamental, precision, accent, display,
decorative, and white boards or chalk boards
 Conditions:
 Additional lighting power allowances used only if the plans clearly
identify all applicable task areas and the lighting equipment designed
to illuminate these tasks
 Tasks that are performed less than 2 hours per day or poor quality tasks
that can be improved are not eligible for the additional lighting power
allowances
 The additional lighting power allowances shall not utilize any type of
luminaires that are used for general lighting in the building
 Up to 1.5 watts per square foot of additional lighting power shall be
allowed in a videoconferencing studio

29. Tailored Method
 Establishes an allowed lighting power budget on a room-by-room or area-by-area
basis
 Provides additional lighting power budgets for illuminating wall displays, floor
displays, task lighting, and ornaments/special effects lighting
 May be helpful when a function area has a high room cavity ratio (RCR)
 To calculate (applicable tables to follow):
 Find the appropriate Primary Function Area
 Find the corresponding General Illuminance Level (LUX)
 Determine the RCR for that primary function area
 Use the RCR compliance form to document the RCR calculation
 Use the General Illuminance Level and RCR to determine the allowed Power Density
Value
 Multiply the allowed Lighting Power Density Value times the square feet of the primary
function areas to get the Allowed Indoor Lighting Power allotment for general lighting for
that primary area
 Specific instructions to calculate Additional Allowed Power based on type of
lighting

30. Tailored Method (cont.)
 Room Cavity Ratio (RCR)
 Must be determined for any primary function area using the Tailored
Lighting Method
 The lighting level in a room is affected in part by the configuration of the
room, expressed as the RCR
 Rooms with high ceiling  more difficult to light  higher RCR  allowed a
higher LPD
 Based on the entire space bounded by floor-to-ceiling partitions
 If task area in larger space not bound by floor-to-ceiling partitions, the RCR of
the entire space must be used for the task area

33. Tailored Method
 Formulas to calculate RCR:
 RCR = [5 X H X (L + W)] / A
 H = room cavity height, vertical distance measured from the work plane to
the center line of the luminaire
 L = room length using interior dimensions
 W = room width using interior dimensions
 A = room area
 RCR = [2.5 X H X P] / A
 H = room cavity height
 A = room area
 P = room perimeter

37. Performance Approach
 The performance approach provides an alternative method to the
prescriptive approach for establishing the allowed lighting power for the
building
 Energy use of the building is modeled using a compliance software
program approved by the Energy Commission
 Standard lighting power density for the building is determined by the compliance
software program based on occupancy type, in accordance with either the
complete building, area category or tailored rules
 Standard lighting power density is used to determine the energy budget for the
building
 When a lighting permit is sought under the performance approach, the
applicant uses a proposed lighting power density to determine whether or
not the building meets the energy budget
 If it does, this proposed lighting power density is automatically translated into the
allowed lighting power for the building by multiplying the area of the building

38. Power Adjustment Factor (PAF)
 An adjustment, or credit, to the actual installed lighting power in a
space, so that when completing the compliance documentation,
some of the installed lighting power is not counted toward the
building’s total installed lighting load
 Provided when specific lighting controls are installed, as long as they are
not required
 To qualify:
 The controlled lighting is permanently installed general lighting systems
and the controls are permanently installed nonresidential-rated lighting
controls
 At least 50% of the light output of the controlled luminaire is within the
applicable area
 Only one PAF used for each qualifying luminaire

39. PAF Applicable Area
 Partial-On Occupant Sensing Control
 Any area less than or equal to 250 sq. ft. enclosed by floor-to-ceiling partitions; any size
classroom, conference or waiting room  PAF = 0.20
 Occupant Sensing Controls in Large Open Plan Offices
 In open plan offices > 250 sq. ft.  one sensor controlling area:
 No larger than 125 sq. ft.  PAF = 0.40
 From 126 to 250 sq. ft.  PAF = 0.30
 From 251 to 500 sq. ft.  PAF = 0.20
 Dimming System
 Hotels/motels, restaurants, auditoriums theatres
 Manual dimming  PAF = 0.10
 Multiscene programmable  PAF = 0.20
 Demand Responsive Control
 All building types less than 10,000 sq. ft.  PAF = 0.25

Requirements for Luminaire Alterations

44. Additions and Alterations (cont.)
 One popular retrofit product that does save energy is the screw-based
LED retrofit kit, designed to be installed directly into a
recessed downlight not having an incandescent socket
 As a screw-in retrofit, it is not recognized by the standards, either for
reducing luminaire wattage or as an alteration that triggers compliance
with the lighting alterations requirements or triggers compliance with the
luminaire modifications in place
 Do not require Title 24 compliance

45. Additions and Alterations (cont.)
 The following alteration methods do not comply with the requirements
of the standards:
 Luminaires and luminaire housings designed to accommodate a variety of
trims or modular components that allow conversion between incandescent
and any other lighting technology without changing the luminaire housing
shall be classified as incandescent
 Screw-based adaptors shall not be used to convert an incandescent
luminaire to any type of non-incandescent technology. Screw-based

residencies during new construction or major remodeling must have
a CRI of 90 or more to be qualified as high efficacy
 Not all installed fixtures must be high efficacy as the new standards
do allow for a percentage (by wattage) of Low Efficacy fixtures to
be installed as well
 The requirements for high efficacy LED luminaires do not apply to
most nonresidential lighting function areas, except for inside
dwelling units of high-rise residential, hotel/motel, fire stations and
dormitory/senior housing
 Ceiling fan light kits with permanently installed LEDs must also meet
the new 90 CRI requirement to be classified as high efficacy

50. CRI (cont.)

limit but the new CA Title 24 has increased the percentage of high
efficacy fixtures required in some rooms
 Bathrooms – required to have one high efficacy fixture with any other
lighting controlled by vacancy sensors
 Garages, laundry rooms and utility rooms – all lighting must be high
efficacy and controlled by vacancy sensors
 Outdoor lighting (all lighting mounted on buildings) – all luminaires must
be high efficacy or controlled by a motion sensor plus a photocontrol or
time clock

51. CRI (cont.)
 Low efficacy outdoor lighting must be controlled by the following:
 A manual on/off switch that doesn’t override to on
 A motion sensor not having an override or bypass switch that disables
the motion sensor, or a motion sensor with an override switch that
temporarily bypasses the motion sensing
 A photocontrol, astronomical time clock or energy management
control system that does not have an override or bypass switch
disabling the control and is programmed to automatically turn the
outdoor lights off during daylight hours

54. Compliance and Enforcement–
Overview
 Beginning January 1st, 2015 new requirements for a documentation
procedure called registration will go into effect
 Required for the construction and alteration of nonresidential buildings
 All nonresidential energy compliance documents will need to be
registered with a nonresidential data registry prior to submittal to an
enforcement agency

55. Compliance and Enforcement
Process
 Design - at the design phase architects, engineers, and designers must understand both the
requirements and the underlying intent of the Standards if they are to design buildings and
systems that are inherently energy efficient and cost effective
 Permit Application - at the permit application, the design team must make sure that the plans
contain all the information that the building official will need to verify that the building or system
satisfies the requirements. (see compliance forms and worksheets)
 Plan Check – during plan check, the building department plans examiner must verify that the
building or system satisfies the requirements of the Standards and that the plans (not just the
compliance forms) contain the information to be verified during field inspection
 Construction – the contractor must carefully allow the approved plans and specification and the
building department field inspector(s) must verify that the building or system is constructed
according to the plans and specifications
 Acceptance Commissioning – after completion of construction, the contractor and/or design
team must properly commission the building and its systems and provide information and/or
training to the building operators on maintenance and operation of the building and its
equipment
 Operation – After occupancy, the building and its systems must be correctly operated and
properly maintained. In addition, building users must be advised of their opportunities and
responsibilities for savings energy

56. Commercial Lighting Compliance Process

57. Commercial Lighting Compliance Process
1. Mandatory Measures are required regardless of the compliance
method selected
2. Select a method for complying with the standards
1. Complete Building, Area Category or Tailored
2. This will determine how many watts of lighting power are allowed to be
installed in the building
3. Calculate the actual lighting power installed by totaling all of the
lighting installed in the building
4. Subtract lighting control credits
1. This process will demonstrate the adjusted actual watts of lighting power
that has been installed in the building
5. If the lighting power that is allowed to be installed in the building, is
equal to or greater than the adjusted actual watts installed, then the
lighting in the building complies with the Standards
1. If it doesn’t comply, then the lighting power will need to be reduced or
additional lighting credits will need to be acquired
